To all whom it may concern:

Be it known that I, HENRY L. Dr; ZENG, States, residing in have invented a new and of Pennsylvania,

of which the following is useful Illuminator,

, a specification.

ing

My invention relates to a new and useful illuminator and consists in providing a source of light, a suitable light conductor and and the conductor for the purpose of transmitting the light to the ob ect.

'It further consists of an electric lamp hava lens-tipped globe and a suitable light conductor for the purpose of transmitting.

light to the object.

It further consists of other novel features of construction, all as will be hereinafter fully set forth. 4

Figure 1 represents a artial elevation and partial sectional view 0 an illuminator emodying my invention. Fig. 2 re resents a sectional view on line :c-x, Fig. 1. igs. 3 and 4 represent sectional views of a portionof illuminators showing some of the forms of light conductors which may be employed.

My invention is designed for the purpose of transmittin a strong light to the object without the lig t source coming in close contact therewith. It is particularly adaptable to sur ical and pathological diagnosis and genera opticalwork. y

In the drawings, I have shown a construction for carryin out my invention but it will be evident t at other instrumentalities may be employed and the arrangement of the parts maybe varied and I do not therefore desire to be limited in every instance to the exact construction as herein shown and described but desire to make such changes therein as may be necessary.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawin illuminator having a hand e 2 which may be of any suitable material and size into which is led, in any suitable manner, the conductors 3- which are adapted to'be connected with a suitable current supply.

4 designates an electric lamp which is screwedor otherwise secured in the handle, the globe of which, in the present instance, is

s, 1 designates an I a lens 5 which serves as a light condenser and concentrates the volume of lilglg: passing through the end of the lamp 6 designates a coupling which is adapted to be screwed or otherwise secured to the handle and to surround the lamp.

7 designates a tip which is preferably formed 0 hard rubber and which has a portion thereof adapted to engage with the coupling 6 so that the latter serves as a support for the tip, the latter having a head or shoulder 8 to prevent improper positioning of the parts, it being understood that the tip 7 can-be adjusted in position'in the coupling to provide for different length lamps 4. Carried by said tip is a light conductor 9 and in the drawings, I have shown the same as a glass rod, the same being of suitable proportions to (properly conduct the light. It will be note that the inner end of the rod 9 is tipped w suitably situated with respect to the lens 5,

so that the latter will concentrate and direct ra s of light into the rod or conductor Which wil project the light from the end thereof, making a very powerful light from a low voltage lamp, 7 becoming heated, so that the instrument is adapted for optical andv sur ical work without danger to the patient. It will be understood that the tip and coupling in one piece.

From the above it will be seen that by having a suitable source of light, a light conductor and a lens supported between the light source and the li ht conductor, I obtain an instrument of t e highest efficiency. .In lieu of making a rod 9 of solid glass, I may employ a tube 10 as shown in Fig. 3 with closed ends, with the same results, or, as shown in Fig. 4, the light conductor may be formed of a tube 11 open at both ends and the tip and coupling may be of one piece, as above stated. The 1i either plain or silvere as desired.

Having thus described my invention, what I claim as new and desire to secure by Let- Y ters Patent, is

which prevents the parts from can be made ht conductors may be 2. In a device of the character described, an electric lamp having a lens tipped globe, a support for said lamp,-a tip carried by said support, and a glass conductor carried by said tip.

3. In a device of the character described, an electric lamp having a lens-tipped lobe, a support for said lamp a tip carried y said support, and a glass conductor carried by said tip and projecting beyond the end thereof.

4; In a device of the character described, a handle, an electric lamp connected With-said handle, a lens carried by said lamp, a tip connected with said handle and a glass rod carried by said tip.

5. 1n 3. device of the character described, a handle, an electric lamp connected with said "handle, a lens carried by said lamp, a coupling connected uith said handle and surrounding said lamp, a tip connected vrith said coupling, and a glass. rod carried by said
